Here's one to knock off the list

C110 from 5,3,253+ has factors:-

prp43 factor: 1095206305187780277368883410987520128364031

I'll finish off the C93.
Should be easy after the C110.

C93 from 5,4,247+ has factors:-

I have begun 4,3,302+.

The tables have been updated again and will be uploaded to my web site shortly.

There are 34 new factors this time and the number of remaining composites is now 231, or 24 fewer than before.

An ECM miss:

Won't have to snfs this one :grin: :

Only 1992 curves at B1 = 3e6, and then:

This one was luck, but you knew that. :rolleyes:

Neat! In case you were wondering, the lucky group order is

2^2 3^5 29 1021 3089 13267 159469 257221 492083 1696417 364436767
